Failing kmod build on rawhide

[Gianluca Sforna]

Thanks to Jarod Wilson, I sorted out the sysprof-kmod build for F-7.
Now something different happens on rawhide:

http://koji.fedoraproject.org/koji/getfile?taskID=78762&name=root.log

No Package Found for kernel-devel-i686 = 2.6.23-0.45.rc0.git16.fc8
No Package Found for kernel-PAE-devel-i686 = 2.6.23-0.45.rc0.git16.fc8

But I checked and the other kmod we have right now in Fedora built
correctly against those variants:

any hint?
